Specification of Letters Patent.

Application filed August 21, 1908. Serial No. 449,661.

T 0 all whom it may concern:

Be it known that we, ALBERT GALE and Doc M. LILLEY, citizens of theUnited States, residing at Bonham, in the county of Fannin, State ofTexas, have invented certain new and useful Improvements inAir-Brake-Setting Appliances; and we do hereby declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

The present invention relates to improvements in air-brake settingappliances, and it has forits principal object the provision of anexceedingly simple, inexpensive, and eflicent apparatus arranged forconnection in such a manner with the stern of an airdischarge valve withwhich the train-pipe is provided that the actuation of the apparatuswill be effected automatically when one of the trucks of the car becomesderailed. With this end in View, the appliance, briefly described,comprises a rock-shaft located beneath the floor of the car and journaled in brackets secured thereto, a pair of depending stirrupsfastened to the bent ends of the shaft and arranged to embrace the axlesof the truck, and a lateral arm carried by the shaft and connectedthrough a retractilc coil-spring with the valve stem.

The referred embodiment of the invention is i lustrated in theaccompanying drawings, in which corresponding parts are designated bythe same reference characters throughout the views thereof.

Of the said drawings, Figure 1 is a fraginental side elevation of abox-car equipped with the improved brake-setting appliance. Fig. 2 is anenlarged pers ective view of the appliance,oas well as of t 10connections between the latter and the valve stem.

Referring more particularly to the drawings, 1 designates generally thecar, and 2 the frame of one of the trucks carried thereby. 3 indicatesin like manner, the train pipe, and 4, the axles of the truck wheels 5.he pipe 3 is provided with a brake-valve (:3 of any ordinary type, thevalve body (not shown) being connected with an operating lever 7.

The brake setting appliance which forms the subject of this inventionconsists primarily of a rock shaft 8 journaled in depending brackets 9,secured to the floor of the car,and operating connections between saidshaft and the valve lever, these connections being hereinafter fullydescribed. he ends of the rock shaft are bent laterally in the samedirection, as indicated by the numeral 10, and each bent end is formedwith a series of perforations in which is interchangeably fitted a splitpin 11, which is likewise arranged to pass through the perforationsformed in the bent upper end of a depending stirrup 12, said stirrupsbeing adapted to embrace the axles 4. T he inner arm of each stirrup hasa length considerably in excess of that of the other arm, and it is thefree end of this longer arm that is bent upon itself and is formed withthe perforations through which the split pin 11 passes, each of saidbent cnds straddling the corresponding bent end of the rock shaft.

Adjacent one end, the rock shaft has socurcd thereto, a collar 13, uponwhich is formed an upwarllly-extcnding lateral arm 14, whose free endhas a perforation formed therein. This arm is connected by a split pin15 with a U-shapcd clip 16, the legsof which are perforated as shown, topermit the adjustable connection of the clip and said arm. The big-htportion of the clip has socurcd thereto an eye-bolt 17 to which isfastened the lower end of a retractilc coil spring 18, whose upper endis connected by a link 19 with the valve lever 7.

Owing to this construction, and to the particular arrangement of thevarious parts of the appliance, as above described, it will be apparentthat when either pair of wheels leaves the track, the frame of the truckwill also drop, carrying with it, the stirrups 12. This downwardmovement of the stirrups will effect the rocking of the shaft 8, owingto their connection with the bent ends 10 thereof. The actuation of therock shaft, in turn, will cause the arm .14 to swing downward, thusrocking the valve lever and opening up communication from the train pipeto the atmosphere, the air under compression in the pipe being thus freeto escape and set the brakes throughout the train.

What is claimed is:

1. The combination, with a car truck and its wheels, of a brake-valveand its stem; a rock-shaft located above the truck and provided with alateral arm; connections between said arm and the valve stem, saidconnections including means for normally holding said stem in positionto close the valve;

and a depending actuating member secured to each end of the rock-shaft,said members being arranged to engage the axles of the truck Wheels.

2. The combination, With a brake-valve and its stem, of a rock-shaftprovided with a lateral arm; connections between said arm and the valvestem, said connections including means for normally holding said stem inposition to close the valve; and a depending stirrup secured to each endof the l'OClQ-Sllitfb.

3. The combination, with a brake-valve and its stem, of a 1'oel;sl1aftprovided intermediate its ends with a lateral arm, and having its endsbent laterally in the same direcl tion; connections between said arm andf the valve stem, said connections including means for normally holdingsaid stem in posiltion to close the valve; and a depending g stirrupsecured to each enn of the rock-shaft. I In testimony whereof, WeELIlilX our signa l tures in presence of two Witnesses. l ALBERT GALE.
